No Service..No Features on Product as promised

I have recently purchased a 55k680UHD TV. I have called the technical call center a number of times to enquire on the basic features which is sold on the TV. For one the YouTube functionality does not work.. the app loaded on TV does not Work eg.vimeo. I have called the call center on Saturday to find out how to download the google play store for my tv model .spoke to Rookshana who told me they have standby staff but will get back to me. no response. called again spoke to bradely who said he escalated query and get back to me. no response...here is the online article that says the tv supports play store.. [URL Removed] the reception to register tv .was told I will get a call Monday to let me know whats happening as local website is problematic... no response. I have purchased a product for a substantial amount of money due to features advertised on the site..The TV is sold with non of the features active. I call the call centre and always told someone will get back to me and I get no response. It is not my duty to chase after the call center agents I expect the company to have some integrity and try to give me the services that I paid for.
